Significant Accounting Policies [Text Block]	NOTE 1 Basis of Presentation The accompanying condensed consolidated balance sheet as of December 31, 2017, Preparing condensed consolidated financial statements requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue and expenses. Examples include estimates of loss contingencies, product life cycles and inventory obsolescence, bad debts, sales returns, share-based compensation, forfeiture rates, the potential outcome of future tax consequences of events that have been recognized in our financial statements or tax returns and determining when investment impairments are other-than-temporary.

Title and risk of loss generally pass to our customers upon shipment. In limited circumstances where either title or risk of loss pass upon destination or acceptance or when collection is not two may We provide product warranties with varying lengths of time and terms. The product warranties are considered to be assurance-type in nature and do not 606, not A variety of technical services can be contracted by our customers for a designated period of time. The service contracts allow customers to call Qualstar for technical support, replace defective parts and to have onsite service provided by Qualstar’s third Our professional services include consulting, engineer and design services. Because control transfers over time, revenue is recognized based on progress toward completion of the performance obligation. The method to measure progress toward completion requires judgment and is based on the nature of the products or services to be provided. The Company generally uses the input method to measure progress for its contracts because it best depicts the transfer of assets to the customer, which occurs as the Company incurs costs for the contracts. Under the cost-to-cost measure of progress, the progress toward completion is measured based on the ratio of costs incurred to date to the total estimated costs at completion of the performance obligation. Revenue is recorded proportionally as costs are incurred. Costs to fulfill these obligations include labor and subcontractor costs. Deferred service revenue is shown separately in the condensed consolidated balance sheets as current and long term. At September 30, 2018 $818,000. December 31, 2017, $927,000. Legal and Other Contingencies The outcomes of legal proceedings and claims brought against us are subject to significant uncertainty. An estimated loss from a loss contingency such as a legal proceeding or claim is accrued by a charge to income if it is probable that a liability has been incurred and the amount of the loss can be reasonably estimated. When legal costs that the entity expects to incur in defending itself in connection with a loss contingency accrual are expected to be material, the loss should factor in all costs and, if the legal costs are reasonably estimable, they should be accrued in accordance with ASC 450, Fair Value of Financial Instruments The carrying amounts of the Company's financial instruments, which include cash equivalents, accounts receivable, accounts payable, related party, and other long-term liabilities, approximate their fair values. Accounting for Income Taxes We estimate our tax liabilities based on current tax laws in the statutory jurisdictions in which we operate in accordance with ASC 740, may not 50% 740 We maintain a valuation allowance to reduce our deferred tax assets due to the uncertainty surrounding the timing of realizing the benefits of net deferred tax assets in future years. We have considered future taxable income and ongoing prudent and feasible tax planning strategies in assessing the need for such a valuation allowance. In the event we were to determine that we would be able to realize all or part of our net deferred tax asset in the future, the valuation allowance would be decreased accordingly.

Expected volatilities are based on the historical volatility of the Company’s stock. The Company uses historical data to estimate option exercise and employee termination in determining forfeiture rates. The expected term of options granted is estimated based on the vesting term of the award, historical employee exercise behavior, expected volatility of the Company’s stock and an employee’s average length of service. The risk-free interest rate used in this model correlates to a U.S. constant rate Treasury security with a contractual life that approximates the expected term of the option award.
